Alright, so I have this stupid problem which I cannot seem to solve, and I think I have insufficient information.

We have this truck.


Some insane guy wants to bike on that wall. After some attempts, I have discovered that the truck's acceleration required for such a feat is 5.88 m/s^2. The weight of the truck is 5320kg. The friction coefficient between the bike's wheels and the wall is 1.7.

Now the question is, what is the static force of friction between the truck's wheels and the road with such an acceleration (5.88 m/s^2). I have no clue where to begin. The information I have is not even related, except for the acceleration. Is it even possible to find it?

    The force that accelerates the truck is easily calculated from ma. And the def'n of friction is mu times normal force, that's it. It's a trick question because you're just calculating the co'eff friction is this case but typically one calculates the limit where the tires would skid ( which is not the case here). If you calc mu= 1.whatever the max mu at skidding is greater. – PhysicsDave yesterday
